MACE-HNE FOR CUTTiNG PATTERNS.

SPEGFXUATION forming part of Letters Patent No. 691,203, dated January 14, 1902.

Application filed April19, 1900. Serial No. 13,505. (No model.)

To LZZ whom t may concern:

Be it known that l, JAMES SULLIVAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Machine for Cutting Patterns, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a machine so constructed that a knife may be used in connection with a feed and be given a vertical movement and to so secure the knife and construct the machine to which the knife is attached that the point of the knife will not rise above the feed.

Another purpose of the invention is to provide a machine having a presser-foot, a feed, and an attached knife and to so arrange the parts that the knife may be employed for cutting fabric in any desired number of layers along the outline of any desired pattern.

The invention consists in the novel construction and combination of the several parts, as Will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a portion of a sewing-machine and a section through the table of the machine and the feed mechanism, which section is taken on the line 1 1 of Fig. 2, the mechanism of the machine being especially adapted to vertically operate and receive a knife. Fig. 2 is a vertical section taken practically on the line 2 2 of Fig. 1. Fig. 3 is a transverse section taken substantially on the line 3 3 of Fig. 1; and Fig. 4 is a plan view of the table of the machine and the feed mechanism, the knife being in transverse section.

The machine illustrated is a sewing-machine adapted to receive a knife and permit said knife to pass through the feed without interfering with the movement of the latter.

A represents the head of the machine, B the presser-bar to which the presser-foot 10 is attached, having the usual longitudinal opening 11, and C represents what is usually known as the needle-bar, to which a knifeblade D is secured in anysuitable or approved manner. This knife-blade extends through a suitable opening in the throat-plate of the machine, which plate is attached to the table 12, and the free end of the said knife is made to pass through the opening 16, made in a feed 13, which feed is illustrated as attached to a bar 14, controlled in one direction by a spring 15 and controlled in the other direction by a lever 15, the feed 13 having the usual reciprocatiu g movement and likewise the usual vertical movement,'the latter movement being secured by means of a cam 18, attached to a drive-shaft 17, which cam engages with a bar 19, connected with the lever 15, as shown in Fig. 1. The shaft 17 stops at the cam 18, and the said cam is located at a point one side of the feed mechanism 13.

The operative portions of the machine are practically the same as a sewing -machineg but the shuttle mechanism is entirely omitted. The drive-shaft is therefore made much shorter than in ordinary sewing-machines, so that the said drive-shaft 17 will not interfere with the knife D as it is vertically reciprocated by the movement of its carrying-bar O. The knife D is of such length that when the carrying-bar C is in its upper position the point of the knife D will be below the feed mechanism, as illustrated in Fig. 1.

The shifting-lever 15 may be operated in any suitable or approved manner. As illustrated .in Figs. 2 and 4, the shifting-lever is provided with a crank between its ends, engaged by a roller located on a bar 21, which bar has suitable guided movement and is connected with a wrist-pin located on a cam 20, which cam is secured to the drive-shaft 17.

It will be observed from the foregoing description and from the drawings that a single piece of material 22 or a number of pieces of material may be placed upon the table 12 over the feed and held on the table by the presserfoot 10 and guided so that the knife will cut through the material as desired; but the presser-foot may be raised at will and said material maybe held and guided entirely by hand,so that the cutting edge of the knife may follow the outline of the pattern, and thus cut a number of pieces of fabric or a single piece of fabric into any desired shape. The machine IOO is especially adapted for cutting large patterns, such as awnings or other articles made from canvas or heavy material.

Having thus `described my invention, I claim as new and desire to secure by Letters Patentl.v A machine for cutting patterns, coinprising a table provided with an opening, a vertically-reciprocating knife in said opening, a feed-plate at right angles to said knife, a reciprocating rod upon which said feed-plate is mounted, aheart-cam and a lever connected thereto for actuating said reciprocating rod in a longitudinal direction parallel with the table, a spring for 'actuating said rod in the opposite direction, and a heart-cam for actuating said feed-plate in a direction at right angles to the table.

2. A machine for cutting patterns, comprising a table provided with an opening, a

vertically-reciprocatingknifein said opening, a feed-plate at right angles to said knife, a reciprocating rod upon which said feed-plate is mounted, a heart-capl and alever connected thereto for actuating said reciprocating rod in a longitudinal direction parallel with the table, a spring for actuating said rod in the opposite direction, a heart-cam for actuating said feed-plate in a direction at right angles to the table, a reciprocating plate located between said heart-cam and said reciprocating rod, and means for actuating said reciprocating plate longitudinally in either direction,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
